What is the value of plancks constant?
The value of Planck's constant is approximately 6.626 x 10^-34 m^2 kg / s. It is a fundamental physical constant that relates the energy of a photon to its frequency.
How are the energy and frequency of electronmagnetic radiation related?
The energy of electromagnetic radiation is directly proportional to its frequency. This relationship is described by Planck's equation: E = hν, where E is the energy, h is Planck's constant, and ν is the frequency. This means that as the frequency of electromagnetic radiation increases, so does its energy.
What is the energy of a photon having a frequency of 410E 7 hz?
The energy of a photon can be calculated using the formula E = h*f, where E is energy, h is Planck's constant (6.626 x 10^-34 J.s), and f is frequency. Plugging in the values, the energy of a photon with a frequency of 4.1 x 10^7 Hz would be approximately 2.72 x 10^-26 Joules.
If the frequency of ultraviolet light is 2.53 x 10 power of -7 plancks constant is 6.63 x 10 power of -34 and the work function is 3.6eV what is the maximum kinetic energy?
The maximum kinetic energy of the emitted photoelectron can be calculated using the equation: KE = hf - work function = hc/λ - work function . Substitute the given values, where h is Planck's constant, f is frequency, c is the speed of light, and λ is the wavelength. Find the maximum kinetic energy by calculating the difference between the energy of the incident light and the work function.
How are wave speed frequency and wave length related to the wave amplitude?
Wave speed, frequency, and wavelength are independent of wave amplitude. Wave speed is determined by the medium through which the wave is traveling, frequency is the number of oscillations per unit time, and wavelength is the distance between two consecutive points in phase. Amplitude, on the other hand, is the maximum displacement of a wave from its equilibrium position.
What do you need to know to calculate the frequency of a wave?
wavelength since frequency =hc/lambda h=plancks constant and c=velocity of light
What was Niels Bohr's formula?
(E) Photon=E2-E1= hv h=Plancks constant v=frequency
What is the value of plancks constant?
The value of Planck's constant is approximately 6.626 x 10^-34 m^2 kg / s. It is a fundamental physical constant that relates the energy of a photon to its frequency.
What is the base unit of Plancks constant?
Planck's constant relates the energy level of radiation due to electrons moving from one energy level to another, by the formula Energy = (Planck's constant) x (frequency of radiation). Therefore the dimensions of Planck's constant are (energy)/(frequency) which means Joules x seconds In fact Planck's constant = 6.67 x 10-34 joule.seconds.
Why LED is used to determine planks constant?
LEDs (Light Emitting Diodes) are used in determining the Planck constant because they emit light at specific frequencies when electrical current is applied. By measuring the voltage needed to produce light of a known frequency, the relationship between energy and frequency can be studied, allowing for the accurate determination of the Planck constant.
Is gas constant equal to planks constant?
No, gas constant is having a value of 8.314Jk-1mol-1 Whereas plancks constant has a value of 6.6*10-31
How are the energy and frequency of electronmagnetic radiation related?
The energy of electromagnetic radiation is directly proportional to its frequency. This relationship is described by Planck's equation: E = hν, where E is the energy, h is Planck's constant, and ν is the frequency. This means that as the frequency of electromagnetic radiation increases, so does its energy.
A photon has a frequency of 4.0 multiplied by 104 Hz?
I assume the equation you're looking for is E=hv or E=hc/lambda. h is plancks constant and c is speed of light in m/s. lambda is in metres
How can you determine the frequency of a light wave?
to find the frequency of a light wave you need to know its wavelength. The frequency is equal to the speed of light (3x10^8 m/s) divided by the wavelength in metres. Alternatively, if you were given the energy of each photon of light in joules you could just divide the energy by plancks constant (6.63x10^-34) to leave you with the frequency in Hz.
What is the energy of a photon having a frequency of 410E 7 hz?
The energy of a photon can be calculated using the formula E = h*f, where E is energy, h is Planck's constant (6.626 x 10^-34 J.s), and f is frequency. Plugging in the values, the energy of a photon with a frequency of 4.1 x 10^7 Hz would be approximately 2.72 x 10^-26 Joules.
Which dimensional formula contains speed of light plancks constant and gravity?
Such a melange of dimensions would involve length3 mass2/time4 .Not only has it no physical significance, but, fortunately for all of us,there is no such formula.
What was Max Plancks biggest invention?
The Quantum Theory.
